| # Wrapper for the add_library() function that allow to require more than a | |||||
| # single library type. The type can be STATIC, SHARED or both. | |||||
| # | |||||
| # LINK_LIBS applies to all the types and follow the syntax of | |||||
| # target_link_libraries(). | |||||
| # OUTPUT_NAME allow to redefine the library output name. If not set the target | |||||
| # name is used. | |||||
| # OBJLIBS can be used to add sources from object targets by using the | |||||
| # $<TARGET_OBJECTS:target> generator expression. | |||||
| # | |||||
| # This function makes 2 variables available to the caller space, named after the | |||||
| # supplied name suffixed by _static_lib and _shared_lib. These variables contain | |||||
| # the actual target name respectively for the static library and the shared | |||||
| # library. If both are not build, the corresponding variable is not set. The | |||||
| # value of these variables can be tested with `if(TARGET ${foo_static_lib}` to | |||||
| # determine if the desired version has been defined and what is the target name. | |||||
